For years, physicists have been trying to design clocks that can measure tiny durations of time with extreme precision. Quantum clocks, in particular, have pushed the boundaries by using the strange ...

The oldest fossilised remains of complex animals appear suddenly in the fossil record, and as if from nowhere, in rocks that ...

This month, the Bulletin of the Atomic Scientists at the University of Chicago is scheduled to announce whether the hands of its famous Doomsday Clock will move closer to midnight.

A panel of scientists and scholars said Thursday they believe the world is as close as it has ever been to a so-called doomsday scenario. The Bulletin of Atomic Scientists, which has been tracking the ...

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

Dinosaur eggshells, once treated as background scenery in fossil digs, have turned out to be some of the most precise ...

Time moves differently on Mars — not in the Tibetan philosophy sense of the word, but in a measurable, physics-will-ruin-your-mission kind of way that's giving NASA engineers a real headache. As the ...
